  • If not code or documentation contributions, then well-written bug reports. Seriously, the quality of bug reports sometimes leaves a lot to be desired. And I don’t necessarily mean a full back-trace attached – and please, if you ever send a back-trace, copy-and-paste the text, never a screenshot – but just details like: system details, OS, version, step-by-step instructions to reproduce that a non-coder could also understand, plus what you expected to happen versus what actually happened.

    This stuff (usually) comes naturally to programmers and engineers, but users don’t necessarily see things this way. I sometimes think bug reports need to adopt a “so tell me what happened?” approach, where reporters are encouraged to describe free-form what they think of the software, then providing the specific details that developed need. That at least would collect all the relevant details, plus extra details that no developers thought to ask.

    Even just having folks that help gather and distill details from user reporters on a forum is easing a burden off of developers, and that effort should be welcomed by any competently-organized project. Many projects already have a template for reports, although it often gets mistaken for boilerplate. Helping reports recognize that they need to fill in all the details is a useful activity that isn’t code or docs.







  • I’m not any type of lawyer, especially not a copyright lawyer, though I’ve been informed that the point of having the copyright date is to mark when the work (book, website, photo, etc) was produced and when last edited. Both aspects are important, since the original date is when the copyright clock starts counting, and having it further in the past is useful to prove infringement that occurs later.

    Likewise, each update to the work imbues a new copyright on just the updated parts, which starts its own clock, and is again useful to prosecute infringement.

    As a result, updating the copyright date is not an exercise of writing today’s year. But rather, it’s adding years to a list, compressing as needed, but never removing any years. For example, if a work was created in 2012 and updated in 2013, 2015, 2016, 2017, and 2022, the copyright date could look like:

    © 2012, 2013, 2015-2017, 2022

    To be clear, I’m not terribly concerned with whether large, institutional copyright holders are able to effectively litigate their IP holdings. Rather, this is advice for small producers of works, like freelancers or folks hosting their own blog. In the age of AI, copyright abuse against small players is now rampant, and a copyright date that is always the current year is ammunition for an AI company’s lawyer to argue that they didn’t plagiarize your work, because your work has a date that came after when they trained their models.

    Not that the copyright date is wholly dispositive, but it makes clear from the get-go when a work came unto copyright protection.


  • I’m not a physicist. But I did live in an apartment at university, and shortness of funds plus hot weather meant experimenting with various box fan configurations.

    What I found most optimal was to open two windows on opposite sides of the dwelling, with the one box fan aimed outward, using cardboard to block the openings around the fan. In my case, the choice of egress (ie air flowing out) window was based on: the window which best fit the box fan’s shape, proximity of noise to the bedroom, and the quality of the window screen.

    As for why the fan points outward, this sends the heat of the motor (60-100 W) out of the dwelling, rather than drawing it in. Also, if facing inward, the high airflow at the tips of the fan blades would tend to draw small flies into the dwelling. But if the fan is at the egress window, then the ingress airflow will average out over the full surface area of the ingress window, producing a lower peak airflow rate, akin to a gentle breeze.

    If you have a multi-floor unit or house, it would be optimal to place the fan at the highest egress window, to take advantage of heat naturally rising. Opening multiple ingress windows will quickly cool those rooms, while also reducing the peak ingress airflow and resulting drafts (eg blowing papers off tables). Of course, it’s necessary to open all the doors to form a path between the ingress and egress windows.


  • The original reporting by 404media is excellent in that it covers the background context, links to the actual PDF of the lawsuit, and reaches out to an outside expert to verify information presented in the lawsuit and learned from their research. It’s a worthwhile read, although it’s behind a paywall; archive.ph may be effective though.

    For folks that just want to see the lawsuit and its probably-dodgy claims, the most recent First Amended Complaint is available through RECAP here, along with most of the other legal documents in the case. As for how RECAP can store copies of these documents, see this FAQ and consider donating to their cause.

    Basically, AXS complains about nine things, generally around: copyright infringement, DMCA violations (ie hacking/reverse engineering), trademark counterfeiting and infringement, various unfair competition statutes, civil conspiracy, and breach of contract (re: terms of service).

    I find the civil conspiracy claim to be a bit weird, since it would require proof that the various other ticket websites actually made contact with each other and agreed to do the other eight things that AXS is complaining about. Why would those other websites – who are mutual competitors – do that? Of course, this is just the complaint, so it’s whatever AXS wants to claim under “information and belief”, aka it’s what they think happened, not necessarily with proof yet.


  • Sources: Aviation Stack Exchange

    If a citation is going to point to any of the Stack Exchange Q&A pages, it is extremely important to specifically cite the exact post or answer, since – not dissimilar to Wikipedia – the quality, consistency, and biases of Stack Exchange answers is paramount for evaluating the information presented, especially factual data to be fed into an infographic.

    I personally am intrigued at these $800 economy, ten-hour flights, as well as a total omission of freight cargo in the underbelly. As presented, this flight has 180 passengers and runs for ten hours. This would suggest it’s not a common narrow-body, either the Boeing 737 or an Airbus A320, as even their largest available configurations can’t fit 180 people in a 2 class setup, let alone a 3 class setup. It could possibly be the Airbus A321, though.

    My point is that if it’s a widebody aircraft or the A321, not hauling cargo would be some staggering malfeasance for a commercial revenue airliner. But I can’t follow-up on any of these queries, since the sources aren’t properly cited.


  • Absolutely, it is essential to always run the numbers. I was once offered a sizable rebate if I accepted a non-0% car loan, but no rebate if I paid cash or had my own financing. Since their loan had no early-repayment penalty – and I demanded this in writing – I accepted their loan and paid it off upon the first statement.

    My suspicion is that that sort of offer was to boost the commissions earned by the loan brokers, rather than to move cars. Or maybe both. Who knows.


  • 0% interest offers show up fairly frequently in the USA, often as general-purpose credit cards, or for car or furniture payments, in addition to the many buy-now-pay-later services that allow financing almost anything. However, the motives for offering 0% are slightly different for each of these products.

    But answering the question directly, a 0% offer is beneficial if you were already going to make the purchase and would finance it. Cheap credit makes it easy to overspend, since the payments will be “tomorrow’s problem”. For people who can afford to pay for something in full, it might still be beneficial to finance with 0% just to conserve cash on hand. But the tradeoff is having to service the debt with regular payments; missing one payment can cause the debt to resume at an exorbitant rate. It takes a decent amount of financial discipline to make a 0% offer work in your favor.

    Going back to why 0% offers even exist, I’ll use furniture and cars as they’re the historic examples. Furniture is expensive, whether it’s a sectional sofa or a queen-size bed with frame and storage. There’s also a sizable markup for furniture, and competition between furniture stores is strong. Thus, to help entice people to buy furniture, sellers will offer 0%, outsourced to a loan company, with the loan subsidized by some of the profit margins.

    For cars, the equation is slightly different. Sure, cars are an order of magnitude more expensive, but that also means the opportunity cost for dealers to offer 0% is correspondingly larger. Instead, 0% financing for cars is almost always subsidized by the manufacturer, not the dealers. This is a financial and business strategy that allows a car company to create more sales in a given quarter, if perhaps they need to meet certain year-end targets but are reluctant to reduce their list prices.

    0% car loans induce more sales fairly quickly, but will draw on the company coffers in the years to come, because the loan company still wants their cut to be paid by someone. Consumers will usually benefit from these offers, as it’s rare for people to buy a new car outright.

    It’s my opinion that if a car company has to subsidize loans to move their product, that’s a tacit admission that their product is wrongly priced or the competition is better. I would take this into consideration, although it wouldn’t necessarily carry the day when considering a purchase. After all, car payment interest is not insignificant.



  • This entire series by Cathode Ray Dude is a wonderful dive into the world of PC boot sequence, for the folks interested in a touch of embedded architecture. His delivery is also on-point, given the complexity and obscurity of the topics.

    From this video alone (41:15):

    The way this worked was: they installed Xen hypervisor on your PC, put Hyperspace in a VM and Windows in another. Now, you either know what a VM is – and I don’t need to explain why this is terrifying – or you don’t and I need to make you understand so you never independently invent this.

    And (43:59):

    This is just a bad idea, ok? Virtualization belongs in data centers. Putting some poor bastard’s whole OS in a VM is a prank. It’s some Truman Show shit. It’s disassembling the coach’s car and putting it back together inside the gym. It’s not remotely worth the trouble and it probably didn’t work.

    I am not an expert bike mechanic by any means. With that said, I can’t quite visualize how re-truing the whole wheel will address a rotor rubbing issue.

    The rotor mounts onto the hub at one of the most durable parts of the assembly, adjacent to the bearings. Generally speaking, the act of truing a wheel is to manipulate the rim so its axis of rotation matches the axis of the hub, where the spokes pull the rim into submission. This process shouldn’t affect the rotor, since that would suggest the hub itself is not spinning true; that could indicate an outright defective hub.

    Are you able to confirm that the disc rotors are true? If the shop built and delivered the wheel with the rotor attached, presumably they checked both rim and rotor for trueness. But if you installed the rotor yourself, you might need to true the rotor.

    If the rotor is true and the whole wheel is true, then that just leaves the brake pads and calipers, which could be misaligned. Although I’m not sure how this would look.


  • There was a ton of hairbrained theories floating around, but nobody had any definitive explanation.

    Well I was new to the company and fresh out of college, so I was tasked with figuring this one out.

    This checks out lol

    Knowing very little about USB audio processing, but having cut my teeth in college on 8-bit 8051 processors, I knew what kind of functions tended to be slow.

    I often wonder if this deep level understanding of embedded software/firmware design is still the norm in university instruction. My suspicion has been that focus moved to making use of ever-increasing SoC performance and capabilities, in the pursuit of making it Just Work™ but also proving Wirth’s Law in the process via badly optimized code.

    This was an excellent read, btw.




  • This might be true, although I do it mostly so I can remove the earplugs and rest them around my neck if someone needs to talk to me.

    The best PPE are the ones which have the fewest barriers toward using. Even the minor annoyance of having to set down untethered earplugs is best avoided, if it acts as a subconscious disincentive towards using PPE. Good safety policy adapts and accommodates this aspect of human behavior.

    In a home workshop, there is no OSHA, so I’m fully responsible for my own safety protocols.



  • I’m nowhere even remotely comparable to a proper furniture maker, but I can tell you some pitfalls to avoid.

    Don’t cut wood without eyes, ears, and face protection. The dust, noise, or fumes will get you one day or another, if without protection. I prefer earmuffs over earplugs, but if earplugs then use the ones which tether both ends together. For a face mask, I like low-profile half-masks like this one: https://www.kleintools.com/catalog/respirators/p100-half-mask-respirator-sm

    Resist the urge to dive into woodworking by starting with reclaimed wood. For example, pallets are a cheap/free source of material, but it’s a hodge-podge of different varieties, all riddled with nail holes, dents, and brown stains from rusty fasteners.

    That’s not to say it can’t be done, but it certainly aggravates the process if you’re just starting. I once came across a section of 2x4 recovered from a pallet, thinking that it would cut just like the pine I was used to. Instead, it wrecked two drill bits and burned a circular saw blade as well as itself. I later mailed a sample of it to the USDA Wood Identification Public Service, who informed me that it was Acer (Hard Maple). Up until then, I didn’t even know that maple came in both varieties.

    It seems hard maple is tougher than nails drill bits. I’m still learning.


  • This sort-of happened in the USA, in a small way, during the fallout of the 2016 Wells Fargo scandal. Public sentiment of the big-name, national retail banks was awful and credit unions capitalized on the moment with advertisements contrasting profit-centric national banks with local, cooperatively-owned credit unions.

    In this article where consultants to credit unions were queried a year later, there’s still some questions as to the long-term effects that may have benefited the credit unions.

    I once came across a comment somewhere online that suggested – sadly without hard evidence – that the scandal may have been a win-win, since the sort of customers willing to uproot themselves from Wells Fargo tended to have smaller balances while still incurring the bookkeeping costs. And that credit unions were able to scale up to take in new customers while saving on advertising dollars.

    It’s a plausible idea, that a new equilibrium would be found in the banking market. Logically extending the idea further, though, would lay bare how much additional integration credit unions would have to do with each other to achieve a truly seamless customer experience. Of course, with more young people mostly sticking to online and mobile banking, this might come in the form of backroom operational improvements, rather than a revamped brick-and-mortar experience.
